当我尝试在 Android 4.2.2 上启动我的项目时遇到问题。这是堆栈跟踪：
08-06 11:00:50.041: E/AndroidRuntime(10606): Caused by: net.sqlcipher.database.SQLiteException: not an error

这在 Android 4.0.4 上运行良好，但是当我在 Android 4.2 上启动时，所有时间都崩溃了。我在官方网站上给出了 sqlcipher 的源代码，我希望这是我使用的最后一个源代码（名称是 SQLCipher+for+android+2.2.0），我没有看到这个项目的最新版本。
提前感谢您的回答（我希望这不是一个重复的问题，因为我搜索并没有找到答案......）

} catch (NullPreferencesException e) {

}
SQLiteDatabase database = SQLiteDatabase.openOrCreateDatabase(path, "123456", null);
db = new SQLiteDatabaseWrapper(database);
daoMaster = new DaoMaster(db);
daoSession = daoMaster.newSession();
